partially 1n longitudinal section, of -the This invention relates to draft rigging for railway cars.A

rlhe principal' obj ect of the invention, generally considered, is to provide a pivotally connected coupler and yoke in railway draft rigging, said yoke being preferably of the vertical type with web portions connecting the forward ends ofthe arms thereof, said web portions serving to limit the pivotal' motion between the coupler and yoke, and means attached to the draft sills for reinforcing said webs upon such pivotal motion.

Another object of our invention is to provide, in a railway draftrigging, a coupler and a yoke with a hooded end on the yoke surrounding the stem of the coupler, and an upright key intersecting said hood and stem for permitting pivotal motion between coupler and yoke, said hooded portion on the yoke serving to limit Vthe pivotalV motion, means being provided on the draft sills adapted to engage'the hooded portion of the oke and reinforce the same.

A further object ofour invention is the provision of a form of yoke for railway draft rigging, which yoke is of a type designated as vertical and provided with forwardly eX- tending arms formed with registering slot portions for receiving a pivotal member, said arms being connected at their forward ends by integral side walls, thereby forming a hol low, open-ended portion adapted to receive a coupler stem and limit pivotal motion between it and the yoke.-

A still further object of our invention is the provision of a draft rigging stop member which is adapted to perform the double func-A tion of engaging and acting as a stop member for cushioning mechanism, and also serve as a centering and reinforcing abutment memlder for the hooded portion of a yoke with which it is ad apted to be employed.

@ther objects and advantages of the invention relating to the particular construction and arrangement of parts, will become apparent as the description proceeds.

lin the drawings. wherein an embodiment of the invention is illustrated, the scope whereof is pointed out in the claims:

Figure l is a view, partially in plan and center or draft sills and associated parts of a car under-frame in combination 'with draft rigging embodying our invention.

Flgure 2 is a central longitudinal vertical sectional'view of the construction shown in F1gure l, parts of the mechanism, however being shown in side elevation; Flgure 3 is an end View of the construction shown in Figure l. Flgure 4 is a transverse vertical section on the line 4--4 of Figure 1, and looking in the direction of the arrows.

Figure 5 is a transverse vertical sectional viewtaken on the line 5-5 of Figure 1, and looking in the direction of the arrows.

VFigure 6 is a top plan view of the lower supplemental guide or carry iron member.

ln the drawings, in which like parts are designated by like reference characters, the numeral lvdesignates the center or draft sills of a car, 2 the rear portion or stem of a coupler, and 3 a yoke member.

ln the present embodiment the yoke 3 is illustrated as of the vertical type and .formed with forwardly extending arms 4 and 5 be'- tween which cushioning mechanism, diagrammatically illustrated by dot and dash lines, is embraced. The cushioning mechanism is here shown provided with a front follower member 6 and a rear follower member 7, said rear follower member abutting against the rear portion 8 of the yoke which joins the arms d and 5 thereof.

For transmitting forces from the cushioning mechanism to the draft sills l, rear stl-op members 9 and 10. which may be of ordinary construction, and front stop members l1 and i2, of special construction to be hereinafter described in detail, are provided. 'llhe rear stop members 9 and 10 serve as abutments for the rear follower member 7 and are preferably provided with longitudinally extending faces 13 and 14, between which the yoke Sis centered.

rllhe forward portions-of the arms 4 and 5 of the yoke are provided with registering slots l5 and 16 for the reception of an upright or substantially vertical-key 17, serving to operatively and pivotally connect the coupler and yoke members. The coupler stem 2 is likewise formed with a slot 18 through which the key 17 passes. The slot 18 is preferably of approximately the same size as the key 17 so that a fairly close fit is obtained, 'whereas the slots 15 and 1G in the yoke arms are preferably flared rearwardly, as illustrated, so that the key is permitted to pivot or angle about its forward edge for allowing corresponding pivotal motion between the coupler and yoke.. For limiting such pivotal motion the forward portions of the arms at and 5 of the yoke, which are preferably widened and increased in depth, as illustrated at 19, to compensate for the slots 15 and 1G therein, are connected at their corresponding side edges by means of upright or substantially vertical web portions 20 aud 2l, which portions are preferabl)v formed integrally with the yoke arms and extend in substantially longitudinal planes parallel to cach other. These web portions 20 and 21 as will be obvious, are engaged by the rearward portion of the coupler stem upon angling or pivotal motion between the coupler and yoke and thereby serve to limit said angling motion.

In order to prevent breakage of these webs 20 and 21, or obviate the necessity of making such webs unduly heavy, the stop members 11 and 12 are formed with stop faces 22, 23. 2st and 25, which extend substantially parallel to and closely embrace the web portions 2O and 21 on the yoke. These stop faces,.as most clearly illustrated in Figure 4. are formed as flanged extensions on the rib or reinforcing web portions 26. 27, 28 and 29 of the forward stop members 11 and 12. It will therefore be apparent that the stop faces 22, 24 and 25, which are engaged by and serve to limit the movement of and reinforce the web portions 2O and 21 on the yoke 3, are preferably integrally connected with the base or main attaching web portion 30 of the respective stop member or casting, by the web portions 26, 27, 2S and 29, respectively. The stop faces 22, 23, 211 and 25 do not need to extend the full length of the stop member, and, as shown in Figure 1, the connecting web portions, therefore, are tapered from tbe ends of said stop faces and gradually merge into the main web 30 of the stop member. All of said stop faces, and their connecting webs, are jointed at the rear end of the stop member by the stop face 31. which is engaged directly by the front follower 6.

Although four stop faces for each coupler web are shown on each stop casting, it is obvious that we do not wish to be limited to this number, as one or any convenient number of such faces may be used. The stop faces are here shown as separated for the more convenient removal of the cores, but it is obvious that they may be made continuous or at least partly continuous, if desired. As illustrated,

however, the said stop faces serve to very materially strengthen the resistingr power of the webs 20 and 21 on the yoke when said webs are engaged by the end of the coupler or coupler stem upon pivotal motion thereof.

The yoke member, as illustrated, may be supported by a yoke support or carry iron 32, near the rear end thereof, and a carry iron 33, near the forward end thereof. Said carry iron 33 also serves as a support for the key 17, as will be understood. An upper yoke guide 34 is preferably provided adjacent the rear end of the yoke. These members 32 and 33 may be connected to the center or draft sills by bolts or other desired fastening means 35. The top guide 34, however, is preferably connected to the top cover plate 3G by means of rivets or other connecting means 37, as illustrated most clearly in Figure 5.

The other portions of the draft rigging and cooperating parts of the car underframe may be of any ordinary or desired construction. For example, the end sill 37ZL is shown as of angle form and connected to the top cover plate 36 in any desired manner. A striking casting is shown at 38 and a coupler carry iron at 39 connected to the striking casting by means of bolts or studs 40 which pass through the ears 11 on the carry iron and through the downwardly projecting flange 42 of the striking casting.

Although in the present embodiment of the invention, the yoke is shown as of the vertical type and the coupler is pivotally eonnected thereto by means of an upright key, it is obvious that we do not wish to be restricted to such construction, as a yoke of a different type may be employed and the pivotal connection between it and the coupler may be of a different character. By virtue of our invention, however, we have provided means by which the upright webs on one of said connected members, which serve to limit the pivotal motion between it and the other member, are efficiently reinforced by means of stop castings positioned on either side of the pivotal connection, which stop castings have cooperating faces which bear against said limiting web portions and reinforce the same as well as provide for transmitting draft forces to the sills. i
